Refactor transport version constants into new file system (elastic#133849) (elastic#133997)

This refactors ZERO, MINIMUM_COMPATIBLE, and MINIMUM_CCS_VERSION into TransportVersion.VersionsHolder and load them from /transport/constants/....

 The transport version used between two nodes is determined by the initial handshake

 The lowest transport version that is compatible with the current node
-is determined by `TransportVersions.MINIMUM_COMPATIBLE`,
+is determined by `TransportVersion.minimumCompatible()`,
 and the node is prevented from joining the cluster if it is below that version.
 This constant should be updated manually on a major release.
 
 The minimum version that can be used for CCS is determined by

+`TransportVersion.minimumCCSVersion()`, but this is not actively checked
 before queries are performed. Only if a query cannot be serialized at that
 version is an action rejected. This constant is updated automatically
 as part of performing a release.
